Re: ModalWindow
I'm also having problems with setting the size of a ModalWindow. It seems the
only way I can affect the height of the window is by setting the initial
height as px which is not an optimal solution because my users have
different screen resolutions.
Here's the code:
infoModal.setCssClassName(ModalWindow.CSS_CLASS_GRAY);
infoModal.setCookieName(null);
infoModal.setResizable(false);
infoModal.setInitialHeight(50);
infoModal.setInitialWidth(50);
infoModal.setHeightUnit("%");
infoModal.setWidthUnit("%");
infoModal.show(target);
I've tried using setUserInitialHeight(true) and setUserInitialHeight(false),
both have the same results.
Now, using a screen resolution of 1680x1050 this window comes up as:
The width, it would seem, is set to "50%" as you'd expect but the height is
not. The dimensions of the window confirm this, 840x665
Using a resolution of 1024x768 the window comes up as:
The dimensions this time are 512x733.
Any help on this would be greatly appreciated.

Re: Cancelling pending Ajax requests
Ideally, I would want to add a small wait period after each key stroke before
the event is actually triggered and throttle the last event if another one
comes in before the time period expires.

Re: Cancelling pending Ajax requests
Does this solution actually work though? I tried it and I don't see any
behaviour I wouldn't get from just the throttle delay. Is there something I
need to change in this to use it? Possibly the channel names?

A problem with paging - Page links not showing up
Hi
I've tried searching for this problem but couldn't find anything useful. My
problem, in a nutshell, is that my PagingNavigation produces empty blocks
where the paging should go. Here's the Java, I'm doing this in the
constructor of a wicket Panel object:
container = new WebMarkupContainer("bookDataView");
DataView bookDataView = createDataView("bookDataRepeater");
bookDataView.setItemsPerPage(5);
AjaxPagingNavigation ajaxPaging = new
AjaxPagingNavigation("paging",bookDataView);
ajaxPaging.setOutputMarkupId(true);
add(ajaxPaging);
container.add(bookDataView);
add(container);
On the HTML side:
cut out a bunch of here
Now, I tested the dataview and it returns data just fine, well over 5 items.
View source shows this:
The paging is just empty :s. Any idea what's going on here?

Re: Quick follow-up
Thanks for both replies.
Oliver: setOutputMarkupPlaceholderTag() calls setOutputMarkupId().
Martijn: That explains a lot :)

Quick follow-up
I managed to solve that problem, but i still cannot get the markup id to show
up in my div.
These two calls:
products.setMarkupId("productlist"+item.getIndex());
products.setOutputMarkupPlaceholderTag(true);
don't seem to do anything. I can change the class of the div just fine with
a SimpleAttributeModifier, but for the div id i can't get it to work.

Wicket id vs. markup id (wicket-1.3.0-beta4)
Hi all
I've been using Wicket for a while now and i love it to death. Today i
encountered a perplexing problem which i haven't been able to get around. My
goal is simply to create a link that shows/hides a div when clicked, and to
create the id of that div dynamically. What i am doing now is this:
JAVA:
final ProductListView products = new ProductListView("items",
order.getItems()); // Just a ListView basically
products.setMarkupId("productlist"+item.getIndex()); // Set the markup id
to hide/show the component
products.setOutputMarkupPlaceholderTag(true);
add(products);
add(new AjaxFallbackLink("toggle"){ // Link to do the toggling.. calls a
javascript function with the id to toggle it
@Override
public void onClick(AjaxRequestTarget arg0) {}
}.add(new AttributeModifier("onClick", true, new
Model("javascript:return
toggleDiv("+("productlist"+item.getIndex())+");";
HTML:
# Click me!
..some stuff here...
So that should add the component with Wicket id "items" and the markup id
"productlist0" (for example). When the page is rendered this error pops up:
WicketMessage: Unable to find component with id 'items' in [MarkupContainer
[Component id = panel, page = web.page.authenticated.IndexPage, path =
2:tabs:panel.DefaultPanel, isVisible = true, isVersioned = true]]. This
means that you declared wicket:id=items in your markup, but that you either
did not add the component to your page at all, or that the hierarchy does
not match.
Now to me, that looks like it's using the markup id i set as the wicked id
of the component. Any ideas?
